Add a `Copy Address` function to the user dashboard

[gravenp]

Add a Copy Address icon + function to the user dashboard so users can easily access their address. This will be especially helpful when Web3Auth social methods are used to sign-in/create a wallet.

• Add the Content Copy icon next to the user's address https://fonts.google.com/icons?icon.query=content+copy
  • Add a tool tip "Copy Address"
• When clicked, copy the user's full address to their clipboard
• This can be added to the develop branch first then included into our Safe hackathon branch
  • Reminder: On the Safe branch, this address will eventually be the Safe and not the Signer address
